Application filed December 26, 1917. Serial No. 208,813.

combustible mixtures 1n internal combustion --englnes One of the objects of my invention is to provide means for indirectly utilizing some of the heat exhausted from the cylinder of an engine for improving the combustible qualities of the fuel charge ot' engines of this character.

Another object of my invention is to provide means, automatically operable, for introducing ancillary charges ot' relatively, rapidly combustible fluids into the cylinders of engines to promote thecomhustible activity of the power charge by'shortening the flame-time of combustion of the charge, or the decrease of duration of time within Which to lcomplete combustion,

Other objects of myinvention are vto gen! orally improve devices of this character whereby the ancillary charge, to be taken into the cylinder, to accelerate the time oi" iniiammation of the power charge is aceoniplishcd automatically, preferably, b v the, suction effect of the engine.

Other and further objects of my invention will become readily apparent, to persons.

skilled in the art, from a consideration of the following description when taken in conjunction with the. drawings, wherein Figure l is a side elevation of an internal combustion engine showing my device connected thereto. v

Fig. 2 is a longitudinal central section through the device.

Fig. 3 is a cross section. taken on line .33 of Fig. 2. l

In all the views the same reference characters are employed to indicate similar parts.

The propagation of the Haine, or the complete infiammation ot' the usual combustible power-charge, in the cylinder of an internal combustion engine, is relatively slow. unless compressed to ahigh degree. in which event the ex ansion activity is enhaneed.`but under suc conditions pre-ignition of the charge is liable to occur, thereby depreciating the power value of the charge, to ay 'greater extent ,than the advantages afforded by the lugh compresslon. The expansion eect of such a charge, t the charge be tired or` heated to the 4kindling point at many places throughout its volume, will tend to increase the powerfvalue of the charge by rendering more complete combustion in a given time, but such a, procedure is rendered practically inexpedient by the introductionof complication into the modeof operation.

In my invention I automatically introduce into the cylinder of an engine, with the power charge, an ancillary charge composed, in part, of an aqueous vapor accompanied by a component of oxygen which mixes with the carbon of the Apowercharge to form a powerful explosive compound. This gas combines with a larger quantity of oxygen than any other and its combustion, when mixed with oxygen, produces a more intense heat than is afforded 'by the usual combustible-material. Being lighter than the gas composing the major charge of the engine, and its particles being of superior mobility, it readily and quickly mixes with the power charge, the efi'eet of which is to shorten the period of time necessary for complete combustion of the power charge and to enable the charge to absorb the excess-ive carbon that would otherwise be present in the power charge and be liberated and deposited as freecarbon upon the valves andother working parts within the c vlinder oi the engine.

In the drawings, I have shown one embodiment of my invention. in `which 5 'is an engine of the internal combustion type, 6 iS the intake manifold, 7 is the exhaust manifold, 9 is a part of the water circulating system and 10 is a carlnlreter. all of which are' common in engines of this general cha' "er.

The device 12. shown in enlarged detail inv Fig. Q, consists ot" an elbow 1.8; for insertion in the intake manifold, a tube I4, in which a valve 15 is yieldingly held seated by a. spring i6. The valve is preferably conical and eloses'both ot the ports 17 and 18,

by the resilient etieet ot' the spring 16. @ne or more perforations- 19, open to the atmosphere, are provided in the tube portion 14,

between the ports 17 and 18 i"or admission of air. A conduit tubef() is connected onto y v water, circulating in the 23 that is controllable by a rod 2e extending to the instrument board of an automobile,

and is adapted to be manually manipulated. The heat from the exhaust products of com- I creased opening of the throttle valve of the carbureter 10,A when the engine is running at a relatively high speed, so that the tendency within the pipe 2O toward opening the valve 15 is substantially constant and the effect of the sprino; is substantially uniform.

When the suction effect, due to the inspiration stroke of 'the engine, opens the valve lo, vapor `or steam will pass through the pipe 20; through the ports 17 and 18, into the .tube 14, and from thence through the conduit 25 into the manifold 6. At the saine time air will enter the ports or openings if) and Ibe drawn through the ports 17-18 mixing thoroughly with the hydrogen coining through the tube 20, before it enters the manifold G, there to be brought into contact with the inwardly moving power charge which now contains the gases or fluids of the ancillary charge. T he latter charge takes up a part of the carbon oi? the power charge in the manifold 6, and' is distributed throughout the power-charge within the cyl inder of the engine by a process ot transpiration, rendering the power chai-ge much more infiaann'iable than otherwise and there fore shortening the time of complete co1nbustion of the power charge.

Imperical demonstration has confirmed the conclusion thatzifvthe time required for complete combustion of the power charge is shortened, and thereupon all of the fuel is consumed, that the expansion, produced by the increased temperature, will be greater and the power eliiciency of the fuel correspondingly increased.

The quantity of Water to be evaporated and to forma constitdent part of thc ancillary charge, may bbe varied by the manual operation of the valve :23, through the instrumentality of the rod 24 from the driver-s seat in the automobile, and by the salue means the water may be entirely shut od, if desired, as when starting the engine.

The strength of the spring 16 may be varied iby the threaded art of the tube 14 andthe part 27 of the el ow, and secured in adjusted position by the check nut 26.

While I have herein shown and described inseam a single embodiment of my invention, for the purpose of clear disclosure, it. manifest that changes may be made in the struc-4 ture within the scope of the appended claims.
